Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used to check the accuracy of the machined part, such as the smoothness of the cut surface, the presence of scratches, the meshing of gears, or the degree of fitting of the cylinder, when processing metals, etc. This invention relates to an oil-based coloring composition that is applied to areas to be checked.

It is known that such a composition is made by dissolving an oil-soluble resin in a volatile solvent such as Betrol to obtain viscosity during coating, and then dividing the pigment into a fraction. Therefore, if some time passes after application, the coating film dries, reducing confirmation accuracy.

Furthermore, it becomes difficult to remove and is inconvenient to handle.

In addition, there is a risk of fire, etc., and it has drawbacks that are not desirable in terms of occupational health and environment.

The present invention aims to solve these drawbacks, and it is possible to obtain a high fKg concentration without the risk of the composition drying out, and it is easy to remove after confirmation, and furthermore, it does not use a volatile solvent. The object of the present invention is to obtain an oil-based coloring composition that has a low risk of fire, etc. and is advantageous in terms of occupational hygiene and environment.

That is, the present invention relates to an oil-based coloring composition characterized by containing polybutene and a pigment.

This was discovered by the inventor as a result of various investigations.

Polybutene is a liquid polymer that does not have a canned, unflavored, or poisonous taste, but is extremely stable under normal conditions without oxidation, hardening, or other quality changes. Various grades of polymers of isobutene, polymers of isobutene, and copolymers of normal butene and isobutene can be used.

Specifically, the molecular weight is d 00-5000 and the viscosity is 80c.
ps (20° C.) up to a high consistency.

However, in terms of ease of application and confirmation accuracy, the viscosity of the vehicle is 500 to 2,500 cps (at 20℃).
) is preferable, and a polybutene within the above range is used alone. Alternatively, a plurality of polybutenes having different viscosities may be used in combination, such as using a mixture of high-viscosity polybutenes and low-viscosity polybutenes that do not fall within the above range.

Furthermore, for example, for high viscosity polybutenes that do not fall within the above range, non-volatile mineral oils such as liquid paraffin and spindle oil, non-drying oils such as olive oil and castor oil, or plasticizers that are compatible with polybutenes such as dioctyl adipate. It is possible to adjust the viscosity to a desired value by mixing them.

In addition, in terms of quality and cost, nonvolatile mineral oil such as liquid paraffin is preferably used for viscosity adjustment.

The amount of polybutene released in the present invention is 40 parts per 100 parts of the composition.
~98 parts or preferably 60 to 80 parts are used.

Confirm whether the dye used in the present invention has been uniformly applied to the processed parts that require confirmation, and also confirm the degree of y-ization of the coating layer after engaging the teeth, etc. It is blended to facilitate machining accuracy and cutting.

The pigments used in the present invention can be composed of one or more of various pigments such as oil-soluble dyes such as Oil Blue BA and Neozapone Blue FLE, inorganic pigments such as navy blue, and pigments such as Palkan Orange and other pigments. The amount used is 2 to 40 parts, preferably 5 to 80 parts, per 100 parts of the product.

Any color can be used as the pigment, but in order to make it easier to check the processing accuracy, we use a color that can clearly contrast with the color inherent to the material of the processed part, such as Ba/L/Oak Orange (C, Summer-NC1211f). ;0) 1Ii=0)
rJ' = color system or I is preferably a blue system such as Prussian blue (C, 1, I rainbow 77510 & 77520), and pigments are particularly preferably used.

Further, the pigment used has a particle size of 5 μm or less, preferably 1 μm or less, so as not to damage the processed surface after coating.

In addition, when the pigment becomes a supercharger, the liquid movement of the composition decreases, making it difficult to apply it to the processed area, and when it becomes too small, the transparency increases, and the difference between the color development inherent to the composition and the material of the processed area becomes small. This may make it difficult to judge the machining accuracy.

In the fine powder invention, one or more known extender pigments such as clay, bentonite, and calcium carbonate are selected as necessary to improve the stability of the quality of the composition and adjust the viscosity of the composition. or used.

The extender pigment is preferably used in an amount of 0 to 50 parts per 100 parts of the composition.
Preferably, 5 to 45 parts are used.

In addition, metal salts of high-molecular fatty acids such as aluminum stearate and magnesium stearate may be used to reduce the civility of the composition, and polyethylene glycol alkyl phenyl ether may be used to improve the dissolution or fractionation of pigments. , sorbitan fatty acid ester, polyethylene glycol alkyl ether, and other surfactants can be used.

To produce the composition of the present invention, for example, a pigment and, if necessary, an extender pigment, a surfactant, etc. are sequentially added to a vehicle adjusted to a desired viscosity in a stirring machine such as a butterfly mixer, and mixed uniformly. The mixture is kneaded using a kneader such as a three-roll mill, and the particle size is adjusted to 5μ or less to obtain a composition of the present invention tb.

Since the composition of the present invention uses polybutene as a vehicle, there is no fear of conversion and solidification, and it is possible to obtain a high-quality IfR+1 degree, and since it is non-drying, it can be easily removed by wiping it with a cloth etc. It is easy and convenient to handle. In addition, there is little risk of fire, etc., and the can is poisonous, making it difficult for workers to survive. J
Kakigami is also good and can do 1 month of use. The composition of the present invention has a viscosity of 40 to 90 m/mφ measured by a final spread meter.
It is preferable to use N:u'Q.

The present invention will be described as theory B based on the following examples.

Example 1 Polybutene HV-15 [R11 product name viscosity 28110 cps, (20'C

15 parts of Palkan Orange (pigment manufactured by Dainippon Ink Chemical Industry Co., Ltd., Shiba@)) were mixed uniformly in a butterfly mixer and then kneaded in a three-roll mill to reduce the particle size to 5 μm or less to obtain an orange oil-based coloring composition.

The resulting composition had a suitable viscosity and could be applied easily and uniformly to the processed area without any smearing. And to check the accuracy, you can clearly distinguish the changes in the paint film, and is it good quality? I
